Who Can Use an AED?

One of the most common questions people have is, “Can you use an AED without training?” The good news is that AEDs are designed to be used by anyone, even those without formal medical training. 

Laws protect first responders in Australia so you don’t need to worry about making a mistake. In case of cardiac arrest it’s always better to do something than nothing.

How to Use a Defibrillator: Key Steps to Follow

Let’s walk through the steps of using a defibrillator in an emergency situation. Remember, while the specific prompts and instructions may vary slightly between different AED models, the general process remains the same.

Step 1: Assess the Scene and Ensure Safety

We don’t want you to end up in cardiac arrest alongside the person you’re trying to save!

Before rushing to use a defibrillator, take a moment to assess the scene for any potential hazards. Ensure that both you and the person in need of help are in a safe location, away from water, metal surfaces, or flammable materials. If necessary, carefully move the person to a safer area to prepare for using a defibrillator.

Step 2: Check for Responsiveness and Call for Help

Check if the person is responsive by gently shaking their shoulders and asking loudly, “Are you okay?”
If there’s no response that’s no good! Call for emergency medical services immediately or ask someone nearby to do so.

Step 3: Check for Breathing

The next step is to check for breathing. If a person is not breathing that likely means they’ve had a cardiac arrest and could need a shock. (Learn more about Cardiac arrest and what a defibrillator actually does in this article)

Australian standards recommend using a test called “look, listen, and feel” to check for breathing

Here’s how it works:

1. Look: Check for any visible signs of breathing, such as the chest rising and falling.

2. Listen: Place your ear near the person’s mouth and nose to listen for breathing sounds.

3. Feel: Feel for any breathing by placing your hand on the person’s chest.


Within around 10 seconds you should be able to tell if they are breathing or not.

Step 4: Begin CPR and Prepare the AED

If the person is unresponsive and not breathing normally, start performing CPR.
Push hard and fast in the center of the chest at a rate of 100-120 compressions per minute and pinch the nose and give 2 rescue breaths for every 30 chest compressions you give.

Step 5: Turn on the AED and Follow Voice and Visual Prompts

Hopefully as you’ve done all this someone should have brought you an AED. Once you have the AED, turn it on. The device will begin providing voice and visual prompts to guide you through the process. Listen carefully and follow the instructions precisely.

Step 6: Prepare the Patient

Before you can give a shock you must remove any clothing covering the person’s chest, including undergarments. If their chest is wet, wipe it with a towelette. If it’s hairy, shave the areas where the pads will go. wipe away any moisture.

Step 7: Attach the Pads

Peel off the backing from the electrode pads and attach them to the person’s bare chest according to the placement diagrams on the pads or the AED.

One pad goes on the upper right side of the chest, just below the collarbone. This pad is usually labeled as the “Upper Right” or “Adult/Right” pad.

The other pad goes on the left side of the chest, just below the armpit. This pad is usually labeled as the “Lower Left” or “Adult/Left” pad.

Step 8: Allow the AED to Analyze the Heart Rhythm

Once the electrode pads are attached, the AED will analyze the person’s heart rhythm. You don’t need a doctor to determine if a shock needs to be given, the defibrillator does this all by itself. The AED will inform you when it’s safe to touch the person again.

Step 9: Deliver the Shock (If Advised)

If the AED determines that a shock is needed, it will instruct you to ensure that no one is touching the person and to press the shock button. Before delivering the shock, loudly announce, “Clear!” to ensure everyone stands back. Once the shock is delivered, the AED will guide you to resume CPR or provide further instructions.

Step 10: Continue Following Prompts and Providing Care

After delivering the shock, continue to follow the defibrillators prompts. If advised, resume CPR, starting with chest compressions. The defibrillator will periodically reassess the person’s heart rhythm and guide you through additional shocks if necessary. Continue providing care until emergency medical services arrive and take over.

By familiarizing yourself with these steps you’ll be well-prepared to use a defibrillator effectively in an emergency.

In the next section, we’ll discuss using defibrillators on different types of people, including children and pregnant women, addressing common concerns and considerations.

How to Use a Defibrillator on Different Types of People

While the general steps for using a defibrillator remain the same, there are some special considerations when using AEDs on certain populations, such as children, infants, and pregnant women.

Using Defibrillators on Infants and Children

One of the most frequent questions people have is, “Can defibrillators be used on infants and children?” The answer is yes, but there are some pointers to keep in mind.


Pediatric AED pads: Many AEDs come with pediatric pads specifically designed for use on children and infants. These pads are smaller and deliver a lower energy shock that’s more appropriate for a child’s body size.

If pediatric pads are not available, adult pads can still be used, but it’s crucial to ensure they do not touch each other when placed on the child’s chest.


Pad placement: For infants and small children, place one pad on the center of the chest and the other on the back, between the shoulder blades. This placement helps ensure the shock passes through the heart effectively.

Using Adult AED Pads on a Child

If pediatric AED pads are not available, you can still use adult pads on a child. However, it’s essential to modify the placement to prevent the pads from touching each other:

  • For children weighing less than 55 pounds (25 kg), place one pad on the front of the chest, in the center, and the other pad on the back, between the shoulder blades.
  • For children weighing more than 55 pounds (25 kg), place the pads as you would for an adult: one on the upper right side of the chest and the other on the lower left side, below the armpit.

How to use a Defibrillator on Pregnant Women

In the event of a sudden cardiac arrest in a pregnant woman, it’s even more crucial to defibrillate quickly. Expectant mothers use more oxygen, so they need to be revived quicker. Also, remember the electricity passes through the heart, not the fetus, so defibrillation can be lifesaving for the fetus.

Defibrillator Use on Patients with Pacemakers or Stents

Some people may have concerns about using a defibrillator on someone with a pacemaker or stents.

  • Pacemakers: Pacemakers are typically implanted under the skin near the collarbone. If a person is unconscious and not breathing chances are the pacemaker is not working properly so they need defibrillation. When placing AED pads, avoid putting them directly over the pacemaker. If you notice a small bump under the skin or a scar near the collarbone, place the pad slightly to the side of it.
  • Stents: Stents are small metal tubes placed in the arteries to help keep them open. The presence of stents does not affect AED use, and you should place the pads in the standard positions.

In an emergency, you don’t need to be overly concerned about who you defibrillate. By understanding these special considerations, you can confidently adapt your AED use to provide the best possible care for infants, children, pregnant women, and those with pacemakers or stents. In the next section, we’ll tackle some common misconceptions and address using defibrillators in special circumstances.

Other Circumstances and Misconceptions

When it comes to using defibrillators, there are several situations that may give people pause or raise concerns. In this section, we’ll address these special circumstances and clear up some common misconceptions to help you feel more confident in your ability to use an AED when needed.

Using a Defibrillator in the Rain or in Water

One common question is whether it’s safe to use a defibrillator in wet conditions, such as in the rain or near a pool. While it’s true that water and electricity don’t mix, AEDs are designed to be safe in these situations:

  • Move the person: If possible, quickly move the person to a dry area before using the AED. If this isn’t feasible, ensure that the person’s chest is dry before attaching the electrode pads.
  • Avoid direct contact with water: When using an AED in wet conditions, make sure you and the person receiving care are not in direct contact with water or standing in puddles.

Using a Defibrillator on a Conscious Person

Defibrillators cannot accidentally shock a conscious person. They detect if a person has had a cardiac arrest and only give a shock then. 

However, if a person is conscious but experiencing chest pain or other symptoms of a heart attack, it’s essential to:

  • Call for emergency medical help immediately
  • Get someone to get the AED so it’s ready should things get worse.
  • Have the person sit or lie down in a comfortable position
  • Keep the person calm and reassure them that help is on the way
  • Do not use an AED until they are unconscious and not breathing

Using a Defibrillator on a Flatline or Someone with No Heartbeat or Pulse

A common misconception is that defibrillators can “restart” a heart that has completely stopped beating, as often portrayed in movies and television.

In reality, when a person has a cardiac arrest often the heart wobbles like jelly for a period. It’s in this period where a shock from an AED can help reset the heart.

If a person is in a flatline, by giving high-quality CPR and getting medication from emergency services there is potential for heart activity to start up again and be successfully reset by a shock.

Can You Accidentally Kill Someone with a Defibrillator?

Some people may hesitate to use an AED out of fear that they might accidentally harm or kill the person they’re trying to help. However, AEDs are designed with safety features to prevent accidental or inappropriate shocks:

  • Voice and visual prompts guide users through the process
  • The AED will only deliver a shock if it detects a shockable rhythm
  • Modern AEDs will not allow a shock to be delivered if the person’s heart is in a normal rhythm

Can You Defibrillate Yourself?

Many people wonder how to use a defibrillator on themselves. While it’s theoretically possible to use an AED on yourself, it’s highly unlikely that you would be able to do so in an emergency situation. If you suspect you’re experiencing a heart attack or other cardiac emergency, call for help immediately and follow the dispatcher’s instructions. Do not attempt to use an AED on yourself.

So set common misconceptions aside. Act confidently and give a shock quick and you can make a big difference in someone’s chance of survival.

Defibrillator Maintenance and Reusability

Proper maintenance and storage of defibrillators are crucial to ensuring they’re always ready for use in an emergency. In this section, we’ll address common questions about defibrillator maintenance and reusability, so you can be confident that your AED is in good working order when you need it most.

Can a Defibrillator Be Used More Than Once?

Yes, a defibrillator can be used multiple times. AEDs are designed to be reusable, and with proper maintenance, they can last for several years. However, there are a few key things to keep in mind:

Replace electrode pads: After each use, the pads must be replaced with new ones. 

Check the battery: You’ll need to replace a battery after a defibrillators used, otherwise many models have 4-7 year standby life and an indicator that will alert you when that time is nearly up.

How Many Times Can a Defibrillator Be Used?

The number of times a defibrillator can be used varies depending on the model and its maintenance. Some models can deliver up to 125 shocks in a rescue. This is helpful because it may take a number of shocks to revive someone, or a person who has been revived may have another cardiac arrest and require more shocks. Most AEDs can be used for multiple rescues, as long as the electrode pads and batteries are replaced as needed.

Proper Maintenance and Storage of Defibrillators

To ensure your AED is always ready for use, follow these maintenance and storage tips:

  • Store the AED in a visible, easily accessible location: Make sure the AED is stored in a place where it can be quickly retrieved in an emergency, such as near a main entrance or in a central location.
  • Keep the AED in its designated case: Most AEDs come with a protective case that helps prevent damage and keeps all the necessary components together.
  • Maintain a stable environment: Store the AED in a cool, dry place, away from extreme temperatures or humidity, which can damage the device or its batteries.
  • Follow the manufacturer’s guidelines for maintenance: Change those batteries and pads when needed!
